Definitions
- the invention relates to a combustion chamber of a gas turbine with a ring-shaped head section, in which a front plate for receiving burners is provided, which are supplied with a primary airflow via annularly arranged air inlet openings in the head section, and wherein the front plate furthermore has heat shields provided in the combustion chamber burner section, which are fixed in place by means of bolt connections.
- the backup points in respect to the flow into the air inlet openings which are formed on the outside of the head section in particular can form a ring within which the air inlet openings are located.
- the center of this ring coincides with the central axis of central longitudinal axis of the annular combustion chamber.
- a gas turbine combustion chamber in accordance with the preamble of claim 1 is represented in U.S. Pat. No. 5,419,115. From this reference it is not possible to discern more clearly how the bolt connections of the heat shields are mounted, but it can be assumed that the bolt nuts of the heat shields are applied to the threaded bolts penetrating the front plate in the space between the front plate and the head section, are introduced through the burner air inlet openings of the head section and are also tightened by means of a suitable tool through these air inlet openings. This operation is comparatively elaborate.
- the attainment of this object is distinguished in that mounting openings for the bolt connections are provided in the head section, wherein the mounting openings are not located outside of the ring formed by the air inlet openings.
- the backup or stagnation points in respect to the flow to the mounting openings which are formed on the outside of the head section can form a ring which does not lie outside of the ring described by the stagnation points of the air inlet openings.
- FIG. 1 represents a partial longitudinal section through a combustion chamber head section with the heat shield mounted
- FIG. 2 shows the view X from FIG. 1,
- FIG. 3a shows the section A--A from FIG. 2,
- FIG. 3b shows the section B--B from FIG. 2.
- the head section of an otherwise not further represented conventional annular gas turbine combustion chamber which has a center axis or center longitudinal axis Z and in which a front plate 2 for receiving burners, not shown, is provided in the customary manner, is identified by reference numeral 1.
- the front plate 2 has several annularly disposed through-openings 3, in which respectively one burner sleeve 4, known to one skilled in the art, is disposed.
- annularly arranged heat shields 6 are provided at the front of this ring-shaped burner section 5, and are supported on the front plate 2.
- each heat shield 6 has several (preferably four) threaded bolts 7, which penetrate through the front plate 2 in respective passages 8, so that on their rear, i.e. in the space 13 between the front plate 2 and the head section 1, it is possible to screw a bolt nut 9 on each threaded bolt 7.
- FIG. 2 The annularly arranged air inlet openings 10 for the burners can be seen in FIG. 2, wherein these air inlet openings 10 are arranged coaxially in respect to the through-openings 3, as shown in FIG. 3a.
- the center lines of the heat shield bolt connections 11 formed by the threaded bolts 7 and the bolt nut 9, are represented by crosses in FIG. 2.
- suitably placed mounting openings 12, i.e. in particular extending coaxially with the bolt connections 11, i.e. coaxially with their center lines, are provided in the head section 1.
- Their design can also be seen in particular in FIG. 3b.
- each bolt connection 11 in a simple manner through these mounting openings 12, i.e. each bolt nut 9 can be simply applied to the corresponding threaded bolt 7, a portion of the primary air flow for feeding the burners, which has reached the space 13 between the head section 1 and the front plate 2, could escape again through these mounting openings 12.
- the mounting openings 12 are arranged in accordance with the following description:
- the backup points S of the mounting openings 10 form a ring, identified by reference numeral 12', when all inside located stagnation backup points and all outside located stagnation points are respectively connected with each other via a circle, whose center is the central axis Z.
- the definition of the rings 12' and 10' can also be made in a simplified manner, i.e. not by means of the stagnation points S, although this definition by means of the stagnation points S represents the physical conditions particularly well and can also explain the desired effect in particular by means of the physical conditions.
- the design in accordance with the invention can also be described in a simpler way in that the air inlet openings 10 themselves constitute a ring 10", within which and not outside of which the mounting openings 12 should be located.
- the outer radius R a of this ring 10" therefore corresponds to the maximum extension R x of the air inlet opening 10 in the radial direction (in respect to the central axis Z), while the inner radius R i of the ring 10" corresponds to the minimum extension R y of the air inlet openings 10 in the radial direction.
- the head section 1 has flow-dynamically designed opening edges 14, which project from the outside to the inside (i.e. into the space 13) in the area of the air inlet openings 10 and in the area of the mounting openings 12, because by means of this the flow conditions, i.e. in particular the inflow of the air flow into the space 13 in accordance with the direction of the arrow X, are improved.
- this can easily be designed in a way differing from the represented exemplary embodiment without departing from the contents of the claims.
